=== 37edo (demonstrated to work but awaiting approval) === | |||
An alternative to the [[Porcupine]] mapping for [[37edo]] are the [[Porcupine_family#Ammonite|ammonite]]/[[Porcupine_family#Porcupinefish|porcupinefish]] [[3L 2s]] (9:5 step ratio) mappings, which also function for [[Subgroup_temperaments#Gariberttet|gariberttet]] (as 37b). The generator for ammonite is 14\37, easily available as one key right plus one key down-right in both versions of this mapping; it functions as a near-just Barbados third (tridecimal semisixth, ~[[13/10]]). The generator for porcupinefish is 5\37, easily available as one key down-right (forward chroma) or one step right (reverse chroma); it functions as an undecimal neutral second (a slightly flat ~[[11/10]] and a sharp ~[[12/11]], tempering out the biyatisma [[121/120]]). The generator for gariberttet is 9\37, easily available as one key right (forward chroma) or one key down-right (reverse chroma); it functions as a near-just tridecimal minor third (~[[13/11]]). [[Bryan Deister]] has used one of these mappings in [https://www.youtube.com/shorts/TEzitpGJvt0 ''37edo''] (2023). | |||
==== Forward chroma ==== | |||
The range is a bit under 7½ octaves, which slope down mildly, with no repeated notes and no missed notes. | |||
{{Lumatone EDO mapping|n=37|start=0|xstep=9|ystep=-4}} | |||
==== Reverse chroma ==== | |||
The total range is just short of eight octaves, but while the middle octaves have no missing notes and a few repeated notes to mitigate vertical wraparounds, the first and last octaves have many notes chopped off at the edges, and the octaves slope down enough to incur a vertical wraparound. | |||
